It is a good and comprehensive guide, it has a lot of animal tracks, I found it a good and complete guide, but honestly sometimes I had a lot of difficult tryng to find some kind of tracks that I found.

In my personal opinion I think that this is a very good book for experts on the field but not so good for beginners in animal tracks. And by the way it doesnt have any color illustration, and altough they are not needed I was very familiar with peterson guides and this one is a little different.

My wife and I have found this guide to be very useful in interpreting the sign left behind by the creatures resident in our northeastern woods, not only tracks but scat as well (with hundreds of detailed drawings of scat it is as much a guide to those leavings as tracks). The extensive behavioral descriptions are equally useful. I am not clear on the basis for the criticisms contained in the other review concerning animal harassment. Dr. Murie was a dedicated conservationist and President of The Wilderness Society after his retirement from the Fish and Wildlife Service and his respect for the creatures he is describing is evident on every page. While he acknowledges that some tracks were obtained from live-trapped animals, it is clear from the book that the overwhelming mass of the data is from direct field observation from a life spent in the outdoors.

very down to earth. dos'nt go into detail

Birders are an odd, if endearing lot, and nowhere is this more apparent (and freely admitted) than in Pete Dunne's Tales of a Low-rent Birder. Since my interest in birding is only casual, the stories that took birding propensities to extremes, such as the hypothetical SVAT team (think SWAT for birds) composed of 4 quirky members who can't agree on anything and spend their lives tracking down bird sightings, and The Legend of Jesse Mew, a play on the guru followed by his adoring disciples thing, were a bit much for me. However, his story of finding, following and eventually pulling on a kit string that wound its way across a bird sanctuary (and thereby causing the entire bird population to take wing when the kite rose into the air) was amusing, as was his story of birding with Roger Tory Peterson. I also enjoyed his attempt to see the world through a peregrine falcon's eyes in "Peregrine Going South for the First Time," and his brief profiles of 4 birders who, though very different people, all share the ability to "see" as told in "A Gift of Vision."

However, none of these stories really hit home for me, meaning I didn't find myself reading eagerly with great interest (as I did with Kingbird Highway by Kenn Kaufman, or The Rites of Autumn by Dano O'Brien), or wishing for more once a story ended. In fact I kept putting the book aside with a feeling of vague dissatisfaction. Avid birders may have another story to tell, but for me this book was a disappointment.

An original writing style and a true love of birds and birdwatching make this one a standout. With sections on eagles, hawks, bluebills and even birdwatchers themselves, this one is a delight for the fellow birdlover.

I've owned this book for a number of years, and have found it really helpful for finding prime birding locations in Ohio. It could stand a little updating, & the maps are not very useful, but the detailed directions of how to get to a location are really useful, when coupled with a DeLorme map for the state.

Thomson's division of the state is also rather odd. There are locations that seem to be arbitrarily grouped into a geographic region that it doesn't seem appropriate to be in.

Overall, it is very useful if you're going to be doing birding in the state and are either a new Ohio birder, or coming from out-of-state to do some birding.

This Flashguide delivers exactly what you would expect. The information found first hand is the most important details needed to identify hawks. Raptors in flight are hard to identify and the guide permits to see the major differences between species. I would recommand it to anyone starting in birding or having difficulties identifying these beautiful birds. Also, the format is practical in the field.

this book helped me TREMENDOUSLY on a report i had to do for biology. it was a great resource! it had so much information in it that i clearly didn't know where to start! i used a lot of things on it. the only reason i didn't give this book a 5, is people unless you think these fuzzy little animals are as awesome as i think they are, u won't really see a point to it! but it's awesome how they tell in detail about penguins. if you need to write a report, it's great! i got an a+ which sky-rocketed my grade!

I foun this one a very good book, it doesnt have any photos, but color illustrations are very descriptive and useful.
Its a must have because it covers all kind of trees, even some palm and cacti.

You wont find any problem to identify any tree, differences are very well noted on this book.

I give it four stars because it doesnt have an overview of trees forms, it only shows leaves, thorns, fruits, but not the tree form and dimensions.

Make a plate-by-plate comparison of the new Waterfowl or Shorebirds guides with the original hardcover editions and you'll see that the sofcover illustrations look like cheap color photocopies. All of the subtlety and detail that made the originals the best field guides of their kind has been lost. Save your money for the used bookstores.

"Waterfowl : An Identification Guide to the Ducks, Geese and Swans of the World" is a wonderful guide for waterfowl identification, with beautiful colored plates of all 155 species of ducks, geese, and swans. A really nice book for everyone who likes wild waterfowl. The only thing I miss are the screamers which are also a part of the anseriformes (waterfowl).

Maybe i'm a little biased but this is a great book.However trying to find a copy was something of a wild goose chase

I own several wildflower identification books, and this one is among my favorites. I often use it in conjunction with other books, but it also does well on its own. I like the fact that the subjects are listed by color - this makes it much easier for me to differentiate species when out in the woods. I have given this book as a gift to flower-loving friends.

I've been teaching in the outdoors using field guides with novices for 18 years, so I offer this advice to assist beginners in choosing a wildflower guide. I have used both this book and the Newcomb book and greatly prefer this one, although Newcomb's is very good. Newcomb's uses a series of keys, which I guess some people find more "sophisticated." Although the key in Newcombs isn't hard to use, I find that the Peterson guide is faster and easier to use in the field. I have also observed that beginners are less likely to make mistakes using the Peterson wildflower guide. The big plus of the Peterson book is the identification system. The flowers are first arranged by color and the book is color coded. Although wild plants may not always be showing their flower colors, 9 times out of ten when the amateur is identifying a flowering plant, it will be in bloom. You can use the Peterson guide to learn the key characterisitics of a blooming plant so that later on when it is not blooming you will still be able to find it in the book and recoginze it.

In the next stage of the Peterson wildflower guide's organization, the plants are arranged by similar visual characteristics. There is a simple outline and description of this system at the beginning of the book. The book utilizes helpful icons, which are featured at the tops of all the descriptive pages for quick thumb-through reference. I have found this icon system very helpful in teaching plant identification because it provides a systematic approach that the beginner can pick up quickly and easily. The Peterson system greatly facilitates intial accuracy of identification at the level of plant family. Once you learn the system of what to look for when observing a plant, the icons allow speed and efficiency when using the book in the field.

At the final stage of identification, the species level, the Peterson guide has excellent written descriptions and the important subtle differences between species are well highlighted, with both text and arrows on the drawings. As other reviewers have stated, the Peterson book has more illustrations than Newcomb, and the highlighted habitat/range descriptions also help in quickly placing a plant. The black and white illustrations are not bothersome since you already know the flower color, and line drawings show key characteristics clearly. The use of illustrations instead of photos is always preferred in a field guide, even though photos seem like a good idea at first glance. A good illustrator shows the plant in the best light and makes sure the key features are visible and prominent.

I have used this book for 20 years to identify wildflowers successfully; the drawings and paintings capture the essence of the flower in a way no photo does; the book includes many less commonly found plants so you are more likely to find what you're looking for; and it is organized by flower color which is most likely to be what drew your attention in the first place. Excellent reference, easily used.

This is the definitive handbook for the rockhound. Nicely updated with more and better pictures to help in identification of rocks and minerals. Too bad that Peterson's decided to save a nickel on the binding -- my copy of "Rocks and Minerals" was splitting out within a week.

I've had other Peterson's Field Guides which were softcover but HARD bound. These are useful handbooks that will last a lifetime.

If you buy a cheap paperback to read once, the binding isn't of much concern. A "field guide" deserves better.

The "Cambridge Guide to Minerals Rocks and Fossils" is just about as good, is about the same price, and has sewn in pages.

This book is arranged according to the mineral classifications, which is good if you know your minerals. The mineral testing section (flame tests, bead tests, etc.) is not found in very many field guides. As a professional Geologist, I would recommend this to other geologists, not to rock hounds. The National Audubon Society's field guide is better for rock hounds; there are more photos and they are arranged by color. The Audubon's minerals are still by classification, but the testing information is not included.

This Field Guide has been, and still is, The classic and useful Field Guide. Despite its title, this is mainly oriented toward minerals. Well organized and interestingly written, this is one of the few mineralogy texts which is both readable for enjoyment, and useful to both the beginner and the expert.

Part I includes an introduction on the philosophy and adjuncts of the collecting and study of minerals, briefly reviews geology and its rocks, discusses the physical properties of minerals (such as may be used to help distinguish the various species), introduces crystallography, a chemical classification of minerals written for the layman, and finally Tests, Techniques, and Tips, with many useful down-to-earth hints.

Part II is Mineral Descriptions, each one with name, formula, crystal system, and visual aids in the plates which include both diagrams and photographs. Several headings in each description are in boldface: Environment, Crystal description, Physical properties, Composition, Tests, Distinguishing characteristics, Occurrence, and Interesting Facts.

Also includes glossary, bibliography, index. Well organized and accurate, this little book has been used by some amateur mineralogists who, although using several more technical books during years of study, still find this one useful. Although another well-known text is the most commonly used one for college mineralogy courses, I have recommended that students also get a copy of the Field Guide. For the amateur exercising a bit of Emersonian self-reliance in the testing of his own specimens, this Field Guide is one of the very few remaining guides including good Tests (which have actually been tried before including them) under each species. Appeals to collectors to first try a few tests on extra material before turning specimens over to others such as over-burdened professionals. Also appeals to study some phase of the subject for ones' own edification and enjoyment, as one will get as much out of it as he or she puts into it. This Field Guide shows you how.

Teensy-weentsy photographs (of which there are few) and tiny drawings do not an identification tool make. Often, the verbal descriptions given for a butterfly do not match, nay, directly contradict the photograph or drawing included! The practice of providing a textual description on one page, a range map (if there even is one) on another, and yet a third page for the descriptive drawing make this a page-turning nightmare.

In short, take this book from your public library - don't waste your money on a very poorly done work.

As an amateur watcher just wanting to know which butterflies were in my garden, I was somewhat disappointed. I spent a great deal of time trying to compare the butterfly with the poorly represented plates. The few pictures scattered through the book were better, but I found errors in the identification given for the picture and the identification given in the plate and one was even not listed on the page they gave (or no where I have yet to find). The range listed were difficult for me to know if this species was in my backyard and not every species had a range map. These errors I found in one whole afternoon while trying to identify only THREE butterflies in my garden. Some of the book I like, like some of the intro information, but I guess other books have this info also. I was frustrated.

I got this from my son who needed a field guide to take to the park and forests. He loves it and so do I. Before we had borrowed our local libraries' 1950 edition of butterfly field guild. What an improvement! Unlike some people we just love it. The pictures are easy to use in the open where you can just notice a few things before whats being observed takes off flying. Opler is very good at listing the most obvious ID factors for each species. And it fits great in a back pack!
